Buying Guide for Battery Charger for Harley Davidson
This section will walk you through a complete guide for buying a battery charger for Harley Davidson. You should consider the following factors in a battery charger so that you end up purchasing the right charger for your Harley. Because the market is filled with various charger brands. One brand is winning in one aspect while another has no competitor in others.
You need to know what benefits will a charger deliver and are they good enough for your Harley Davidson? Does your Harley need such a battery charger? You should cross-check each feature a product could give with your motorcycle.
Key Features for the Best Battery Charger for Harley Davidson Motorcycle
Below are the key features a battery charger should have for quality and safe operation. The first key feature is the charging mode.
Various battery chargers have multiple modes apart from charging. A charger with a trickle mode disallows the charger to transfer current to the battery once it’s fully charged. The float mode, on the other hand, recharges the battery, if it gets discharged again.
Many chargers have a reconditioning mode, which gives life to the dead batteries. You can switch chargers like the CTEK for different usages. If you want to use the charger for a motorcycle battery or a car battery, you can switch it to that mode.
Opt for the battery chargers with multiple modes. It’s better than those with only a single mode. In this regard, you can choose a NOCO brand. Because this product is not only a charger. It’s a maintainer, trickle charger, and battery desulfator.
Another key feature in battery chargers is the connectors. The connectors charge your battery. So you need to see if the connectors of a charger you want to purchase fit the type of battery you have.
Many batteries require alligator clips for charging. Because they’re big enough that they couldn’t be charged without these clamps. Other batteries are placed in such an area in a car where you can’t fit alligators due to their bigger sizes. At that time, you may need an eyelet charger for your battery.
Battery chargers either come with alligator connectors or eyelet connectors. Check out your battery first and see which one will be fit for it. Luckily numerous battery chargers come with both connectors like the CTEK battery charger reviewed above.
For Harley Davidson motorcycles, alligator connectors are fine. Because they are not small enough to connect them with eyelet connectors. The battery charger with alligator connectors is fit for Harley motorcycles.
Reverse Polarity Protection
To save your battery and yourself, you should triple-check this essential aspect in a battery charger. Sometimes people connect a charger with the wrong pole of a battery, unwillingly. This could cause damage to your battery and can hurt you because of a big spark.
Reverse polarity protection is a feature that alerts you when you connect a charger with a battery the wrong way. A red LED will flash in the charger at that moment. Some chargers are more advanced and they can work if you connect the charger with either end of the battery.
If you got the former or latter charger, that’s fine. But don’t buy a charger that lacks reverse polarity protection. The battery chargers we’ve reviewed here have polarity protection features. So this issue has been resolved for you if you buy one of the above products for your Harley Davidson.
Before choosing the best battery charger for a Harley Davidson motorcycle, take a look at the following factors as well.
Volts And Amps
A charger should have the same voltage as your battery. They have to match to deliver smooth performance. A Harley Davidson battery is either 6 volt or 12 volts depending on the motorcycle model. So you need a battery charger with the volt in this range. Visit your owner manual and see your Harley battery’s voltage. Then act accordingly.
The battery chargers mentioned in this article have both 6 and 12 volts. Some chargers like the NOCO GENIUS 10 works for 6 and 12 volt. You can charge your battery with this charger if it’s a 6V or 12V. If you don’t know about your Harley battery voltage, opt for a NOCO charger.
amp. The NOCO charger has the highest amperage on the list, 10 Amp.
Various battery chargers have a thermal sensor to detect if the battery is overcharged or low charged. This is an essential aspect, especially on hot summer days. When you leave a charger and a battery connected, the charger gets heated. It has adverse effects. Choose the type of charger that has a thermal sensor to save both battery and the charger itself.
To know whether your battery is charged or charging or should you unplug the alligators or not, you need some notifications. So that you can act accordingly. Many battery chargers have LED lights for reading. Is it charging your battery or in which mode the charging is running? All these are indicated via LED lights. Some chargers have screens as well.
All the chargers reviewed here have LED indicators, not screens. Digital chargers may cost more than the above products. But both deliver the readings.
Input Power Supply
What AC voltage does the charger you want to buy need? First, you need to plug the charger in to recharge your battery. Is the AC voltage a charger requires available around you or in your home or not? Some chargers need 100 – 120 VAC, while many have 100 – 240 VAC features.
If you buy a charger of 120 VAC, and the local voltage in your area is 240, you’ll need a step-down transformer for the charger. To avoid this headache, check the local voltage in your area and the charger’s voltage if they fit or not.
Multi-Vehicle Battery Charger
This factor isn’t essential for buying a charger for a Harley Davidson motorcycle. But if you buy a charger that you can also charge other batteries with, this is a plus point. You may need it for another car.
Benefits of Motorcycle Battery Chargers
You can win the following benefits when you buy a battery charger for your motorcycle.
A battery charger extends your battery’s life. If your battery is dead, you need to charge it with a charger that not only charges it but maintains and reconditions it. Quality battery chargers alive dead batteries. A thermal sensor battery charger saves your battery from overcharging, which could damage your battery. Hence, extending battery life.
If you use a good battery maintainer, you won’t need to replace your battery with a new one. If the battery is dead to 1 volt, you don’t need another battery but a charger to maintain your battery. So less constant battery replacement.
Battery chargers play a key role in safety. They don’t let the battery get overcharged, which causes severe damage or risk of fire. The temperature monitor senses the heat and reduces charge flow when it detects that the battery is fully charged. Some chargers switch to a float mode after charging a battery, hence reducing overcharge and more safety.
Saves energy and money
A charger saves your money. It disallows you to buy a new battery for your motorcycle. Because it can bring back a dead battery to life. With that, the charger can also save electric energy. It automatically senses overcharging and turns into float mode.
Types of Motorcycle Battery Chargers

These are regular and old chargers that cost less compared to modern chargers. The pitfalls of this charger are that it wastes energy and causes damage to your battery if you don’t unplug it on time.
However, the new charger is way better than the regular chargers. The trickle charger works otherwise. Plug the charger in and it will recharge the battery until it gets full. Upon completion, it opens the circuit and reduces the waste of energy. And all this happens automatically, no manpower required.
Float chargers work the same as a trickle charger. It charges the battery and stops when the battery is fully charged. When the battery’s voltage is reduced, the float charger detects the reduction. It again then charges the battery to fill the gap.
This is a small plus point in float chargers over trickle chargers. The floating occurs automatically.
